摘要

在本文中,研究小组制作了姜黄树脂与纳米银颗粒和壳聚糖结合的生物产品(BN)样品,并研究了影响 BN 制剂生产的因素。具体而言,对 BN 制剂的生产研究成果,包括成分、添加剂、混合比例和技术参数进行了计算和测试,以获得具有最高耐久性和分散性的纳米制剂。实验结果表明,在 5 升/批的中试规模下,最佳生产参数设置为活性成分/添加剂的比例 =3/1,混合过程的最佳温度为 40-45oC,搅拌速度为 500 rpm,时间为 60 分钟。由此,我们成功制备出 18 种 BN1-BN18 制剂样品,颜色从浅黄色到深黄色不等。结果表明,BN1-BN18 产品具有良好的抗真菌活性,且随着姜黄油树脂含量的增加,抗真菌活性逐渐增强。

Research on production and testing of antifungal activity Phytophthora spp. causing fruit rot and Colletotrichum spp. causing anthracnose of silver nanoparticles, chitosan and turmeric resin bioproducts
In this paper, the research team made samples of bio-products (BN) of turmeric resin combined with silver nanoparticles and chitosan and investigated the factors affecting the production of BN preparations. Specifically, the results of research on the production of BN preparations including ingredients, additives, mixing ratios, and technological parameters have been calculated and tested to obtain nano-preparations with the highest durability and dispersion. The experimental results obtained the optimal set of parameters for production at a pilot scale of 5 litres/batch are the ratio of active ingredients/additives =3/1, the optimal temperature for the mixing process is 40-45oC, the stirring speed is 500 rpm, and the time is 60 minutes. From here, we have successfully fabricated 18 samples of BN1-BN18 preparations with colours ranging from light yellow to dark yellow. Antifungal activity was tested against Colletotrichum spp. causing anthracnose disease and fruit rot disease caused by Phytophthora spp., the results showed that BN1-BN18 products exhibited good antifungal activity, and antifungal activity increased gradually when the content of turmeric oil resin increased.
